Description
Product overview of the Dell R1HPD
The R1HPD Dell Perc H800 6GB S PCI-Express 2.0 SAS Raid Controller is a hardware device designed for storage management in a server environment. It provides a high level of performance, reliability, and scalability for large-scale storage needs. The device is equipped with advanced features that enable users to effectively manage their storage infrastructure and ensure data protection.
Understanding RAID Controllers
A RAID (redundant array of independent disks) controller is a hardware device that manages multiple hard drives in a storage system to enhance performance and data protection. RAID controllers are critical in a server environment where data storage and access are paramount. They work by grouping multiple hard drives together into logical units that are managed by the RAID controller.
The main advantage of using RAID controllers is that they provide redundancy and fault tolerance, which is essential for data protection. In the event of a hard drive failure, RAID controllers can rebuild the data on the failed drive from the data on the other drives in the array. This ensures that the data is not lost and that the system remains operational.
Understanding the Dell Perc H800 6GB S PCI-Express 2.0 SAS Raid Controller
The Dell Perc H800 6GB S PCI-Express 2.0 SAS Raid Controller is a high-performance RAID controller designed for large-scale storage systems. It supports up to 192 drives and offers a high level of scalability, making it an ideal choice for enterprise-level storage needs.
The device supports SAS (Serial Attached SCSI) and SATA (Serial Advanced Technology Attachment) drives, which provides flexibility in terms of storage options. It also supports RAID levels 0, 1, 5, 6, 10, 50, and 60, which enables users to configure the storage system according to their specific needs.
The Dell Perc H800 6GB S PCI-Express 2.0 SAS Raid Controller features a dual-core PowerPC processor that provides high-speed data processing and ensures fast system performance. It also has 512 MB of cache memory, which further enhances system performance.
The device supports PCI-Express 2.0, which provides a high-speed data transfer rate of up to 5 Gbps per lane. This ensures that data can be transferred quickly between the RAID controller and the server’s motherboard.
Advanced Features of the Dell Perc H800 6GB S PCI-Express 2.0 SAS Raid Controller
The Dell Perc H800 6GB S PCI-Express 2.0 SAS Raid Controller comes with several advanced features that make it a powerful storage management device. These features include:
- Online Capacity Expansion (OCE)
The OCE feature enables users to expand the capacity of the storage system while it is still operational. This means that users can add new hard drives to the system without having to shut it down, which ensures uninterrupted system operation.
- Online RAID Level Migration (ORLM)
The ORLM feature enables users to migrate from one RAID level to another without having to shut down the system. This means that users can change the RAID configuration of the system according to their changing needs without having to disrupt system operations.
- Battery Backup Unit (BBU)
The BBU feature provides backup power to the cache memory of the RAID controller in the event of a power failure. This ensures that the data in the cache memory is not lost and that the system can be safely shut down.
